  1. 238. Mapping out the Dark Matter in the Milky Way with Stars
    Lina Necib (MIT)
    08/09/2025, 09:50

    In this talk, I will explore the interfacing of simulations, observations, and machine learning techniques to construct a detailed map of Dark Matter in the Milky Way, focusing on the Galactic Center/Halo and dwarf galaxies. For the Galactic Halo, I will present a recent work that reveals a decline in the stellar circular velocity, inducing tensions with established estimates of the Milky...

  2. 224. DESI Peculiar Velocity Survey and the DR1 Fundamental Plane sample
    Caitlin Ross (The University of Queensland)
    08/09/2025, 11:00
    The current Cosmological Model and its Tensions (Theory and observations)
    Talk

    The Dark Energy Spectroscopic Instrument (DESI) Peculiar Velocity Survey aims to provide measurements of the growth rate of structure and the Hubble constant in our local universe. To do so the survey, over the course of its 5 years of operations, aims to measure peculiar velocities for over 186,000 galaxies using both the Fundamental Plane and Tully Fisher relations. Additionally, these...

  3. 221. Needlets and foreground removal for SKAO HI intensity maps
    Bianca De Caro (INAF-IASF Milano)

    Probes of the Universe from measurements - CMB, LSS, and BH of any mass
    Talk

    Intensity Mapping (IM) of the 21-cm line of the neutral hydrogen (HI) has become a compelling new technique to map the large-scale structure of the Universe. One of the main challenges is the presence of strong foreground emissions of several orders of magnitude larger than the HI signal. Here we implement a version of the Principal Component Analysis, a blind component-separation technique,...

  4. 239. Primordial Black Holes -- Positivist Perspective, Quantum Quiddity and Galaxy Genesis
    Florian Kühnel
    08/09/2025, 12:20

    Primordial black holes are black holes that may have formed in the early Universe. Their masses potentially span a range from as low as the Planck mass up to many orders of magnitude above the solar mass. This, in particular, includes those black holes recently discovered through gravitational waves, and (part of) these may conceivably be of primordial origin. After a general introduction on...

  5. 228. RockStar Baryogenesis: Baryogenesis from primordial CP violation
    Dr Venus Keus (Dublin Institute for Advanced Studies (DIAS))
    Fundamental aspects of Cosmology.
    Talk

    I will present a novel Baryogenesis mechanism in which an asymmetry of scalars in a three-Higgs doublet model produced exiting a CP-violating inflationary set-up is translated into an asymmetry of baryons through electroweak instantons.
